NEW QUESTION # 228
A 2-month-old patient is drowsy following generalized tonic-clonic activity. The baby has no medical history and feels warm to the touch. There is a petechial rash on the baby's trunk and extremities. The vital signs are BP 76/50 mmHg, P 120/min, R 24/min, and SpO# 99% on room air. The temperature is 103.1°F (39.5°C). Is the patient more likely experiencing febrile seizure or meningitis, and why?
Answer: C
Explanation:
Febrile seizures most commonly occur in children between 6 months and 5 years of age. NREMT pediatric education emphasizes that seizures in infants younger than 6 months are not considered simple febrile seizures and should raise immediate concern for serious central nervous system infection.
Option C is correct because this patient is only 2 months old, placing them outside the typical age range for febrile seizures. Additionally, the presence of a petechial rash, lethargy, hypotension, and fever strongly suggests meningitis or sepsis, both of which are life-threatening.
Option A is incorrect because fever alone does not confirm febrile seizure.
Option B is incorrect because lack of medical history does not exclude serious infection.
Option D is partially true but not the most accurate or distinguishing reason.
NREMT stresses early recognition of meningitis, rapid transport, and aggressive supportive care due to high mortality risk in infants.
NEW QUESTION # 229
Which of the following conditions would most likely result in pulmonary edema? Select the two correct options.
Answer: C,D
Explanation:
Pulmonary edema is caused by fluid accumulation in the alveoli, impairing gas exchange. It is typically due to:
* Left-sided heart failure: Blood backs up into the pulmonary circulation
* Hypertensive crisis: Increases hydrostatic pressure in the lungs
Anaphylaxis causes vasodilation and bronchospasm, not fluid overload. Increased oncotic pressure would retain fluid in capillaries - the opposite of edema.

NEW QUESTION # 230
A 70-year-old patient has a sudden onset of difficulty breathing with throat and chest tightness after working outside. The EMT auscultates bilateral wheezes. The vital signs are BP 60/44, P 128, R 28, and SpO# 90% on room air. Which of the following treatments should the EMT administer?
Answer: B
Explanation:
The symptoms and vital signs (wheezing, hypotension, high pulse rate, respiratory distress) are strongly indicative of anaphylaxis, which is a life-threatening allergic reaction. Bilateral wheezing and hypotension further confirm systemic involvement. The first-line treatment is intramuscular epinephrine, which:
* Reverses bronchospasm (via beta-2 adrenergic effects)
* Raises blood pressure (via alpha-1 vasoconstriction)
* Improves airway tone and reduces mucosal edema
A metered-dose inhaler may help in mild bronchospasm but is insufficient during anaphylactic shock. Positive pressure ventilations are a secondary measure if respiratory failure occurs. Nitroglycerin is contraindicated due to low BP.

NEW QUESTION # 231
A 65-year-old patient with a history of angina reports chest pain and shortness of breath after playing golf. The patient stated the pain began one hour ago and has not stopped with rest. The vital signs are BP 86/64, P 112, R 22, and SpO# 89% on room air. Which of the following actions should the EMT do next?
Answer: A
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
This is ahigh-risk cardiac eventdue to unstable angina or possiblemyocardial infarction. The EMT should:
* Administer oxygenif SpO# is <94%
* Avoid nitroglycerinif systolic BP is <90 mmHg
* Obtain a 12-lead ECGto identify ST-elevation MI (STEMI) and transmit it if trained and authorized CPAP is indicated forpulmonary edema, and albuterol is forbronchospasm, neither of which applies here.

NEW QUESTION # 232
What components are necessary to maintain adequate perfusion? Select the three correct options.
Answer: B,C,E
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Perfusionrefers to delivery of oxygen and nutrients to tissues. It depends on three essential components:
* Patent airway: Ensures oxygen reaches lungs
* Intact microcirculation: Capillary-level exchange must function
* Sufficient blood volume: Maintains blood pressure and oxygen transport Hypoxic drive relates toCOPD physiology, not perfusion.High alveolar pressure(like from CPAP) may impede venous return, and alow ventilation-perfusion ratiomeans poor oxygenation efficiency, which negatively affects perfusion.
